Magnificent Bastard: Fernando Vidal. He married a young, rich woman, flirted with his mother, befriended her husband, set him against his wife and made the mother and daughter fight over him while doing it.
Nightmare Fuel: on an island Fernando visits in his delusions, there is a gigantic old cyclops as big as the sky, raising from the horizon always looking at you. Also the little gem of a story he tells at some point in the writing in which a couple is leaving their apartment when the caretaker, believing everybody has gone on vacations turns off the electricity and traps them in an old elevator. After trying to eat their own feces, the man kills the woman and eats her, only to starve a little later.
